STRINGED MUSICAL INSTRUMENT.

' Application filed March 11, 1926, Serial No. 93,913, and in Germany April 15, 1925.

It is knownto arrange sounding-bars made of two parts in the interior of hollow stringed musical instruments and to connect said bars by means of a shell while firmly fixing to each of the adjacent ends of the sounding-bar a ground glass body and placing a glass lens between the latter in firm contact therewith.

The present invention has for its object to improve the action of such sounding-bars by not firmly connecting the ground glass bodies with the adjacent ends of the sounding-bar but loosely placing them upon said ends in firm contact therewith only as well as with one another, a separate lens between said bodies being omitted, while the shell enclosing the adjacent ends oi? the soundingbar and holding said glass bodies in place is made of sheet-silver.

Experiments have proved that by this improved arrangement an extremely fine tone of the instrument is attained.

The accompanying drawing illustrates the improvement: Fig. l is a longitudinal central section through a violin fitted therewith, and Fig. 2 is a cross-section of the latter on a smaller scale.

The soundingbar is fastened in the interior of the hollow body 1 of the violin in the longitudinal direction of the latter and made of two wooden pieces 2, 2 the adjacent ends thereof being enclosed by a sheet-silver shell 3 in which two ground glass bodies 4, P are loosely inserted, one at each of said ends, and in firm contact with one another as well as with the adjacent ends of the two-parted sounding-bar.

In the hollow body 1, furthermore, a sound post 5 of known art, is inserted.

lVhat we claim, is':

The combination, in a hollow stringed musical instrument, of a sounding-bar fastened in the interior of the latter and consisting of two wooden pieces, a sheet-silver shell enclosing the adjacent ends of the latter, and two ground glass bodies loosely inserted in said shell, one at each of said ends, and in firm contact with one another as well as with the adjacent ends of the two-parted soundingbar.

In testimony whereof we have hereunto set our hands.
